Was happy running MSB Analog DAC direct to Pass Labs until ...... Krell KSP B7 offered to me for fun demo. Transformed the sound. I am in the no preamp camp because I’m averse to preamp coloration , but this preamp has unnoticeable coloration and saturates my amplifiers very well. I prefer Pass Labs amp over Krell cos Krell sounded “hard “ to me. But this Krell preamplifier synergies very well. I’m wondering if there is a better KRELL PREAMP I ought to search out. Who better to ask than the Krell forum.
